He may play a gladiator on Starz's hit series Spartacus, but when it came time to pop the question, Liam McIntyre proved he's a real prince.

When McIntyre proposed to girlfriend Erin Hasan at Disney World in Florida, he not only dressed up as a prince, but had one of the characters from Cinderella come to Hasan's door and give her a makeover for the special evening. "They had custom-made me a dress based on my three favorite Disney princesses," Hasan told Australia's TV Week. Hasan then attended a private dinner where McIntyre arrived in costume and proposed with a "massive" ring.

"It's got two music notes on both sides, and because I play Glinda in Wicked, Liam imprinted a picture of the wand with a diamond in the middle," Hasan said of the ring. "It was unbelievable," she said of the night. "I knew Liam likes to put on a show but this was amazing."

The couple, who have been dating for two years, plan to wed in early 2014 in their native Australia, according to People.

Spartacus: War of the Damned premieres on Friday, Jan. 25 at 9/8c on Starz.
